SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 470,988, dated March15, 1892.

Application filed January 5, 1392. Serial No. 417,090. (No model.)

To all whom it may concern.-

Be it known that I, I/VESLEY COULTER, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Sash Holders and Locks and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings,which form partof this specification.

My invention relates to improvements in sash holders and locks; and itconsists in the construction, combination, and arrangement of parts,which will be fully described hereinafter, and particularly referred toin the claims.

The object of my invention is to provide a sash' holder and lock whichis secured to the sash and is constructed to have a cog-wheel engage arack placed upon the window-frame, and to provide means for holding andreleasing the wheel from revolving in either direction, and a means forholding the wheel against rotation in one direction, while it allows itto freely revolve in the opposite direction, whereby the window can bera sed or lowered, as the case may be, and held in that position, aswill be more fully described hereinafter.

In the drawings, Figure 1 is an inside elevation of a holder and lockembodying my invention. Fig. 2 is an edge view looking from theleft-hand side of Fig. 1.

A indicates the side rail of a window-sash of a car-window or show-case,for which my invention is especial] y intended, though it can be usedupon any window. Cutin this windowsash ig a cavity or recess B, in whichthe lock is placed, as shown in Fig. 2. O is a base or bed plate of thelock, which has extending therefrom the lugs E, between which a cogwheelD is journaled that has one edge thereof extending through a slot madein the bedplate 0. Pivoted at one side of the said wheel and in a linetherewith is a pawl F, which has one end to engage the cog-wheel and theother end provided with a spring H for holding the pawl in contact withthe said wheel. In this manner the wheel is allowed to revolve freely in.one direction, while it is locked against rotation in the oppositedirection. Hence the sash to which it is attached (if a of thewindow-frame, as will be understood.

For the purpose of lifting the pawl from the cog-wheel D to allow thewindow to drop a lever J is pivoted between its ends to the said plate 0and has a raised portion K, which extends over the said pawl and engagesa projection I upon the upper face thereof. A handle L extends through aslot M of the plate 0, and by means of this handle the lever J isoperated. When the lever is raised, its raised end K engages the pin Iupon the pawl F and lifts it OK of the said Wheel D, so that the Wheelcan revolve freely in either direction. This lever J is returned toposition by means of a spring N, which is wrapped around the pivotal pinof the lever and has one end engage a projection cl of .the plate 0 andits opposite end engage the raised portion K of the lever.

Bymeans of the above-described construction the window-sash can befreely raised and held in the desired position by the wheel and againstrotation in either direction, and thus preventing the sash from beingeither raised or lowered, as the case may be, a lever O is pivoted tothe plate 0 between its ends, one end of which is adapted to be forcedbetween the cogs of the wheel D, as shown in solid lines in Fig. l, andcarried away from the wheel, as shown in dotted lines of the samefigure. This lever is operated by means of a turning key Q, which has areduced end 17 extending through a perforation made in the plate 0. Thisreduced end is screw-tl1readed to receive a nut P and is angular toreceive an operating cam or plate provided with the projections B. Whenthe key Q is turned in one direction, one of the projections R engagesthe lever 0 and carries its opposite end in engagement with thecog-wheel D, and when turned in the opposite direction carries theopposite end of the lever away from the said wheel. In this manner thewheel D is locked against rotation in either direction and the sashfirmly held against movement in either direction, or the wheel isallowed to turn, as desired.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

1. Asash-holdercomprisingabed-plate having a slot, a wheel journaled tothe inner side of the said plate and projecting through the slot toengage a rack, a spring-actuated pawl engaging the said wheel, a leverpivoted between its ends to the said plate, one end of the leverengaging the pawl, and a handle at the opposite end of the lever,projecting through an opening in the plate, substantially as set forth.
